Tried my own hands on Sarabi a long time ago, but I find her too difficult to draw to be honest.

And I think most people seem to silently agree with me on that one, as I do not see much Sarabi-art in general, not even within the TLK-universe. Most Lioness-art is based on cloned Sarafina and/or adult Nala/Kiara based designs..

That said, I think it has to do with keeping it all looking proportionate and natural, which in case of Sarabi is kind of hard to effectively realise.. Atleast for me it is. I always tend to mess her up most horribly to be honest.. So yah.. *shrugs*
